[Bug 876097] Re: update-alternatives: error: alternative ri can't be slave of ruby: it is a master alternative.
My error was similar. After installing or updating any package, among others, this error was included. Setting up ruby1.8 (1.8.7.352-2ubuntu1.1) ... update-alternatives: error: alternative rdoc can't be slave of ruby: it is a master alternative. dpkg: error processing ruby1.8 (--configure): sudo update-alternatives --remove rdoc /usr/bin/rdoc sudo update-alternatives --remove rdoc /usr/bin/rdoc1.8 sudo update-alternatives --remove rdoc /usr/bin/rdoc1.9.2 solved this problem. I used all three commands because all three directories existed. No errors to report during `apt-get update` and `apt-get upgrade` or installing or upgrading any package. Thanks a bunch Leon Maurer!

[Bug 876097] Re: update-alternatives: error: alternative ri can't be slave of ruby: it is a master alternative.
Looks like the solution was running sudo update-alternatives --remove ri /usr/bin/ri1.8 Before that, if I listed the alternatives for ri I'd see: leon@leon-desktop:~$ sudo update-alternatives --list ri update-alternatives: warning: alternative /usr/bin/ri1.8 (part of link group ri) doesn't exist. Removing from list of alternatives. I could run that multiple times, and each time it'd say that it was removing /usr/bin/ri1.8 from the list of alternatives, but it didn't remove it until I told it to with the first command. I'm not sure why all this was necessary. I don't think my installation was special, but maybe it was. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876097 Title: update-alternatives: error: alternative ri can't be slave of ruby: it is a master alternative.
